Description

[Detailed description of the invention] a. Purpose of the invention (industrial application field) A viscous fluid transfer pump having a crushing mechanism according to this invention mixes ground peanuts with starch syrup, sugar, etc., and further crushes the mixture into lumps. It can be used, for example, when transferring peanut butter ingredients containing butter into a filling hopper while crushing the butter lumps.

(Conventional technology) When producing peanut butter to spread on bread, peanuts that have been peeled and ground in advance, starch syrup,
After mixing with sugar and adding chunks of butter,
The butter lumps are crushed and mixed evenly with other ingredients to make peanut butter, which is then transferred to a filling hopper and packed into small commercially available containers.

FIG. 3 shows the production of peanut butter by a conventional method.

That is, a container 2 stores peanut butter raw material 1, which is a mixture of peeled and crushed peanuts, starch syrup, and sugar, and further added chunks of butter.
is placed on a handcart 3 and moved near the chopper 5 on the table 4, and the raw material 1 in the container 2 is thrown into a hopper 7 communicating with the chopper 5 using a ladle 6.

The raw material 1 is fed into the chopper 5 through the hopper 7, which is driven by the motor 8 via the reducer.
The lumps of butter etc. are crushed in this Chiyotsupa 5, and further passed through a filter built in the Chiyotsupa 5 and atomized to form peanut butter 9.
It is sent out from the rear end opening.

The peanut butter 9 thus sent out from the rear end opening of the chopper 5 is received in the bucket 10 and conveyed to the upper surface of a stand 12 provided near the filling machine 11.

The peanut butter 9 in the bucket 10 carried to the upper surface of the stand 12 is transferred to the filling machine 1 again by the ladle 13.

The filling machine 11 measures the peanut butter 9 put into the hopper 14 and passes it through a nozzle 15 provided at the lower end.
A fixed amount is sent out from the container and filled into a small container 43 for sale.

(Problem to be solved by the invention) However, in the conventional method of processing the raw material into peanut butter 9 as described above and then filling it into small containers 43 for sale, the peanut butter raw material 1 or the peanut butter Since the transfer of step 9 is carried out using the ladles 6 and 13 in a state open to the atmosphere, it is not only unsanitary as dust and other substances easily get mixed in during the transfer process, but also the transfer using the ladles 6 and 13 and the bucket 10
Many tasks, such as transporting peanut butter, had to be done manually, which was a factor that hindered the efficiency of peanut butter production. In particular, the task of manually carrying the heavy bucket 10 containing a large amount of peanut butter 9 and placing it on the stand 12 requires strength, and is a difficult task for those who are weak.

According to the present invention, a viscous fluid transfer pump having such a crushing mechanism is configured to suck up the peanut butter raw material 1 from the container 2, further crush lumps in the raw material 1, and then send it to the hopper 14 of the filling machine 11. , which solves all of the above-mentioned inconveniences.

b. Structure of the invention (means for solving the problem) The viscous fluid transfer pump having a crushing mechanism of the invention has a cylindrical stator with coarsely pitched double threads formed on its inner peripheral surface. It has a twisted rod shape with a coarse single-thread thread, and a rotor with a cutter for coarse crushing fixed thereon is inserted into one end exposed from an opening at one end of the stator.

The rotor is rotatably driven by a swing shaft whose one end is connected to the other end of the rotor via a universal joint, and the other end of the feed tube, whose one end is connected to the other end of the stator, has a discharge port on the side. The provided cylindrical casing is connected and fixed.

A circular cutter plate having a circular hole in the center and a large number of small holes around the circular hole is fixed to the inner side of the connecting portion between the housing and the feed tube.

The end of the drive shaft that is rotationally driven by a motor and passes through the circular through hole is connected to the other end of the swing shaft via a universal joint, and the outer peripheral surface of the end of the drive shaft is connected to the cut plate. A rotating radial cutter is fixed close to the side of the blade.

(Operation) When the viscous fluid transfer pump having the crushing mechanism of the present invention configured as described above is used to transfer the viscous fluid while crushing lumps contained in the fluid, the open end of the stator The viscous fluid to be transferred is inserted into a container storing the viscous fluid, and the other end of a transfer passage such as a hose whose one end is connected to the discharge port on the side of the housing is inserted into the inside of a hopper etc. which is to receive the viscous fluid. In this state, the motor rotates the rotor inside the stator.

Since the stator and rotor constitute a single-screw pump, as the rotor inside the stator rotates while swinging around the universal joint, a space exists between the inner circumferential surface of the stator and the outer circumferential surface of the rotor. moves in the length direction of the rotor, and the viscous fluid taken into this space moves toward the feed cylinder.

The viscous fluid containing the coarsely crushed lumps that has moved inside the space toward the feed tube in this way further moves inside this feed tube toward the housing, and the viscous fluid that is present at the inlet of the housing. It flows into the housing through small holes in the plate. When the viscous fluid passes through the small through hole of the cutter plate, the lumps contained in the viscous fluid become large enough to pass through the small hole, and are removed by the rotating cutter in the vicinity of the cutter plate. Shredded. Therefore, no lumps of butter or the like are present in the viscous fluid that has passed through the cutter plate and is fed into the housing.

As long as the rotor continues to rotate,
New viscous fluid is sent one after another, and the pressure inside the housing increases, so the viscous fluid inside the housing is sent from the discharge port into a transfer passage such as a hose, and is sent to a part that receives the viscous fluid, such as a hopper. It will be done.
